PAINT STRIPPER FOR USE ON WINDOWS AND THE LIKE Filed Aug. 25, 1960 2Sheets-Sheet 2 States Pate This invention relates to a device speciallyadapted to strip paint from windows and the like and also for cleaningsuch surfaces.

Hitherto, paint that has got on windows during painting operations hasrequired to be removed by scraping with the end of some sharp tool suchas a knife or chisel. Also various types of handles and adaptors havebeen marketed to enable a razor blade to be used as a scraper. All thesedevices suffered from the defect that the blade area was too small thusrendering the work tedious. In addition, razor blades were liable tobreak.

It is an object of this invention to overcome these de fects byproviding a device with a large blade surface, the said blade beingreversible and adjustable.

The invention may be described as an improved stripper for paint and thelike comprising a blade of rectangular shape of which two opposite edgesare sharpened so as to be reversible within a clamp consisting of twoflat sides which are connected together by a handle along one of theiredges and which are adapted to receive the blade between them with asharpened edge thereof protruding from the edges Opposite to that of thejoined edges, the said sides being formed with slots for the passage ofadjusting bolts which pass through holes in the blade so that the extentthat the blade protrudes can be adjusted.

The invention will now be described with the aid of the accompanyingdrawings in which:

FIGURE 1 is a side elevation.

FIGURE 2 is an end view.

FIGURE 3a is a view of the blade in reduced size.

FIGURE 3 is a perspective view.

FIGURE 4 is a perspective view of a modification.

FIGURE 5 is an end view of the device shown in FIGURE 4.

FIGURE 6 is a side elevation of the device shown in FIGURE 4.

4 The blade 1 is preferably made from spring steel but any othermaterial capable of being sharpened to give a blade that will retain itsedge without frequent sharpening may be used. The blade is in the shapeof a rectangular plate, the longer edges being sharpened to formreversible cutting edges 2 and 3'. The blade has four holes 4, 5, 6 and7 drilled through it at approximately the positions shown in FIGURE 3awhich is on a reduced scale.

The blade holder shown in FIGURES 1 to 3 is in the form of a clamp andis made of a single sheet of plastic or other suitable material andconsists of two similar rectangular side plates 8 and 9 of a size justslightly larger than the blade, these two sides being connected alongtheir upper edge by a substantially oval shaped hand grip 10 formed byan outwardly bulging of the two sides at their connecting edges. Twocorresponding sets of slots 11 and 12 are located in each side of theholder and parallel to each other.

The blade 1 is fitted between the sides 8 and 9 of the holder as isshown in the drawings. Bolts 13 are inserted through the slots 11 and 12and through the sets of the corresponding holes 4 and 5 or 6 and 7,according to which edge of the blade one desires to use, and tightenedat the other side by butterfly nuts 13a. By loosening the nuts andmoving the bolts up or down in the slots a smaller or larger area of theblade may be made to protrude from the blade holder, or the bladeretracted within the holder so that a sharpened edge will not beexposed. The bottom edges of the sides are bevelled as at 14.

The device is used by gripping the handle 10 between thumb and fingersand pushing the blade along the surface of the window or other surfacerequiring stripping.

In an alternative embodiment as illustrated in FIGURES 4, 5 and 6, thedevice is provided with an upright handle 15. In such a case the holdermay be conveniently moulded in two halves which are later securedtogether by joining the handle. In such a case where the device isprovided with a handle the blade area is preferably somewhat smallerthan that of the device shown in FIG- URES l to 3 for convenience ofworking.

I claim:

1; An improved stripper for paint and the like comprising a holder for ascraper blade of a rectangular shape having opposite sharpened edges,said holder comprising a pair of flat plates of a rectangular shape,said plates being joined together along one of their edges to form anoval enlargement and to provide a handle parallel with the oppositeedges of said plates, said opposite edges of the plates being unjoined,said plates each having a pair of slots spaced apart and parallel witheach other and perpendicular to said handle and to the unjoined edges toreceive adjusting bolts passing through holes in the blade and toprovide a 'dual clamping of the two plates against the blade and toprovide a sliding rectilinear adjustment for said blade.

2. An improved stripper for paint and the like according to claim 1,wherein said oval enlargement of the joined portions of the platesincludes a rearwardly projecting main handle portion disposedperpendicular to the oval 5 enlargement forming the parallel handleportion.
